Easiest way for you to figure out your offset is look at your wheels. The offset will be printed on the wheel either around the lug area or on the back side somewhere. Should say ETXX Where XX = Offset number.

In that case you don't worry if you have to increase or decrease it, you just add spacers.

If you want to figure out what your final offset will be, you subtract the spacer width from the wheel ET.

My speedlines are 37 or 38mm

My Focus SVT wheels are 50mm and then I used 10mm spacers to bring the ET to 40mm, so really close to stock.

The Focus SVT wheels with the spacers are near exact stock, they do not stick out at all.

Without the spacers, they sit too far in and rub on front suspension components.
